Why is the 'top to bottom' gospel important for Christians?

The concept of a 'top to bottom' gospel is critical in Reformed theology because it highlights that God is the initiator and executor of salvation. This means that all aspects of salvation are rooted in God's grace and are fully accomplished in Christ’s work on the cross. As stated in Ephesians 2:8-9, it is by grace we are saved through faith, not by works, thus excluding any human effort. The tearing of the veil from top to bottom symbolizes that God alone has opened the way for sinners to have access to Him, demonstrating that our salvation is not contingent upon human actions or decisions. This assurance of salvation rests solely on what Christ has done, providing believers with confidence and a firm foundation in their faith.
